SELF-ADJUSTING AND sniir anvanorne THE Application filed June 20, 1924, Serial predetermined so that the advance will beuniform. The object is to prevent dips or corrugations in the surface and this object is accompplished by making the rollers run at angles over the surfaces. Another object is to provide rollers which are particularly adaptable for use on vilorolithic paving. Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims. I j r p Reference is had to the accompany ng drawings which form a part of this application. j i d Fig. 1 is a planview ofthe general form of the roller and themeans for "operating the roller. Fig. 2 is a similar view, siowing one roller running in a'fposition fixed as to the frame and one roller which changes position in operation. Fig. 3 is a plan view, showing two fixed rollers. Fig. 4; is a plan view, illustratin g a. variation in the frame for operating the self-advancing roller. Fig. 5 is side elevation of a frame showing the slots in the frame for movement of the rollers. Fig. 6 is a plan view, showingtwo self-advancing rollers in one frame. Fig.

Fig. 9 is a front elevation of the adjustable roller. Fig. 10 is a side elevation of the device as shown in Fig. 1 provided with an adjustable handle. Fig. 11 is a side elevation of a jointed frame, showing the" devices which permit a flexing of the frame. Fig. 12 is a plan view of the same.

Similar characters of reference are used to indicate the same parts throughout the several views. j

The principal featureofthis invention is a self-advancing roller 1. A frame, having draft or push bars 2 and 3, and side beams saga rnirasnvianrn 1a. saunas nxncnrnix or SAID ROBERT C. saunas, I r

4, is provided for operating the roller or. rollers. The roller carrylng frame may be operated from either one of the draft mem to niove'the frame from one side of the street or road to the othen clamp 7 may he carried by the members 5 which is adapt;

ed to engage the handle 6 at any required point. The clamp 7 may be'released from the handle 6 so that the handle 6 may be moved'the required distance and then the clamp 7 may be secured to the handle.

The roller 1 may be pivoted to one me1n-: her of the frame 4 at 8. i The roller is mounted on a shaft 9 which is pivotally connect} ed to the frame 4 at 8. The other endof the shaftt) isslidably mounted'in a slot 10 in the frame 4. The connection of the shaft of the roller 1 to frame member 4 may. be any suitable swivel connection. In operation, if the frame ismoved in the direction of the .draft member 2, the roller 1 will dropback to, the dotted outline position 11. When the frame startsback to the other side or startingpoint, the roller 1 will drop back to the dotted outline position 12. The frame members 4 have series ofholesvertically there through and pins 13' are inserted-in these holes to limit the movement or swing of the roller 1. The roller will-advance more onless in making the trip across the street accord ing to. the position of the pins 13. The

swinging of the roller in this manner automatically advances the device on the street. The moving of the roller angularly across the street paving incidentally accomplishes another function and that is, the preventing of the roller from making creases or corrugations 111 the paving. If the roller should .run directly across the street and back over the same track, there would be a: tendency to make creases or corrugations and each time) the" roller should go back over the same track, the corrugations would'bei made deeper and in this manner-would make a rough street. ting the roller tochange directions, the roller will run angularly relative to the previously made impression and thus tend to smooth out any depression previously made.

The roller-frame is provided with a han- With the provision for permitdle 6 which should be relatively long because the smoothing device must be moved entirely across the street and back and some streets and roads will be wider than others.

Thefixcd niember 5 is provided with a clamp 7 which can be loosened for adjustment of the handle 6.

Additional-rollers- 15 may be journaled in the frame members 4 for operating on the surface of concrete or other paving. I The advantage of'the additional rollers is that he edd ionalz q lers run ire y cr the surfaceandthgswinging roller will run at an angle to the other, r'olleror rollers and so smooth -outany depression or cavity that other. rollers might make.

Fig. 4 of the drawings shows a variation in the; means for operating. the roller. consisting of acoinbi ne d.yoke and frame 16, and a handle 17.

2. A concrete finishing device comprising a frame having its side members slotted and roller having a swivel connection with one of said members and having the other end slidably connected to the other one of; said members for, automatic adjustment of said rollers to the required angle.

3. A concrete finishing device comprising and a roller pivotally connectedatoone of I said side members and having theother. end

slidably connected totlie other. side member for. automatic adjustment of said rollers to therequired angleand means for limiting the amount of movement of the slidable end of said roller relative to the frame.
